Our solar system formed over 4 billion years ago from a giant cloud of gas and dust. An explosion from a nearby star created this cloud, and gravity caused the cloud to collapse and spin, forming a dense, hot center that became our Sun. As the cloud flattened, particles stuck together in the outer regions to form planets like Jupiter, while only rocky planets could form near the Sun due to the intense heat. Over time, this process resulted in the current solar system containing the Sun and eight major planets.

2. Basic info!
ǃ Our solar system is 2600 light years from the
center of our galaxy, the Milky Way
ǃ Our solar system is elliptical in shape
ǃ Astronomers think our solar system is over
four billon years old.

3. How It all started!
• An enormous explosion occurred about 13.7
billion years ago
• A star exploded, and it left clouds of gas from
when it lived and heavy metals from when it
died.

5. How it continued!
• This explosion made waves in space which
squeezed the cloud of gas and dust. Squeezing
made the cloud start to collapse, as gravity
pulled the gas and dust together, forming a
solar nebula, or cloud. The cloud began to spin
as it collapsed which caused the cloud to grow
hotter and denser in the center, with dust and
gas surrounding it.

6. Planets and moons!
• As the dust and gas ring got thinner, particles
began to stick to each other and form
bunches. Some bunches got bigger, as
particles and small clumps stuck to
them, eventually forming planets or moons.

7. Planets like Earth!
• Near the center of the cloud only rocky
material could stand the great heat.
• This is where planets like Earth formed.

8. Massive planets!
• Icy substance settled in the outer part of the
cloud along with rocky material, where the
massive planets like Jupiter formed
Storm!

9. Sun!
• Then center finally got so hot that it became a
star, our lovely Sun.
• Then we have a brand new solar system!
